77 Degrees Rooftop is a new bar that offers fun rum drinks that bring the tropics to Austin.

77 Degrees Rooftop opens this afternoon as the third of four original bar concepts from the Union Venture Group, one of the development companies transforming the Domain into such a North Austin hot spot.

“With cocktails designed specifically to make guests feel like they’re on vacation, 77 Degrees is the perfect addition to Rock Rose,” Jeff Van Delden, co-owner of Union Venture Group, said in a press release. “Partying on the roof will be a must for everyone who stops by Rock Rose — the sunsets are a great way to end any day.”

So are the cocktails, which 77 Degrees’ Ryan Baird designed to make visitors feel like they can enjoy tropical fun all year round (and not just at Texas Tiki Week). The drinks include El Niño, with Myers’s Dark Rum, Bacardi Oakheart, lime and ginger beer and the Norman’s Cay with Bacardi Cocnut, Bacardi Mango Fusion, coconut water and lime.

The bar also pays homage to some of the tasty tropical classics, like the Singapore Sling with Bombay East Gin, cherry heering, Bénédictine, pineapple and lime juices, and soda.

Although the drinks are quite boozy, the bar offers bites that will keep you feeling fine. Try the fresh ceviche with lime juice, red onions, avocado and diced sweet plantains served with a spiced wonton chip or the Chickpea Lettuce Wraps with ancho spice mix, lime crema, pickled onions and jalapeño.

And if you stop by from 3 to 7 p.m. Mondays through Fridays, you’re just in time for happy hour. According to the press release, happy hour includes $5 appetizers, $5 wells and $4 Mexican beers. 77 Degrees also has a Party on the Roof event on Sundays from 3 to 8 p.m. And don’t worry about the rain, either: There are both covered areas and open-top spots on the rooftop bar.

The bar is opened daily from 3 p.m. to 2 a.m. and is located at 11500 Rock Rose Ave. (The entrance is located between Jack & Ginger’s and Saint Genevieve.) For more information, visit 77-degrees.com.
